Dec 18, 2010 I probably use Little Snitch more than any other application on my computer. So having it on my new iPad was the first thing I thought about after I purchased it. Especially since there are NO LAWS prohibiting anyone from doing anything with the information they collect from all those cookies. Little Snitch is a firewall application that monitors and controls outbound internet traffic.

With regard to the need for Sophos, see my Mac Malware Guide. There is Mac malware out there, and Sophos will protect you against it quite well, but Mac OS X does a pretty good job itself as well. One class of borderline malware - called adware - is becoming increasingly common, but most of it is not blocked by either Sophos or Mac OS X, unfortunately. Thus it's more important to know how to protect yourself.

Little Snitch is a mixed bag. On the one hand, there has been malware that short-circuited its own install process if Little Snitch was present... thus, just having Little Snitch installed prevented installation, because the hackers behind the malware knew that Little Snitch would prevent it from working properly. On the other hand, some malware has been known to completely disable Little Snitch and go on with its malicious business unimpeded.

None of this malware is still viable, due to updates to Mac OS X. However, because of the possibility of the latter, Little Snitch cannot be relied on. If the malware is already running on your machine, it's too late for something like Little Snitch to be a reliable way of blocking outbound connections. If you choose to use Little Snitch with full knowledge of this limitation, that's fine.

Little Snitch is a host-based application firewall for macOS. It can be used to monitor applications, preventing or permitting them to connect to attached networks through advanced rules. It is produced and maintained by the Austrian firm Objective Development Software GmbH.

Unlike a stateful firewall, which is designed primarily to protect a system from external attacks by restricting inbound traffic, Little Snitch is designed to protect privacy by limiting outbound traffic.^[2] Little Snitch controls network traffic by registering kernel extensions through the standard application programming interface (API) provided by Apple.^[3]

If an application or process attempts to establish a network connection, Little Snitch prevents the connection. A dialog is presented to the user which allows one to deny or permit the connection on a one-time or permanent basis. The dialog allows one to restrict the parameters of the connection, restricting it to a specific port, protocol or domain. Little Snitch's integral network monitor allows one to see ongoing traffic in real time with domain names and traffic direction displayed.

The application (version 4) received a positive 4.5/5 review from Macworld.^[4]
